il Myinventi'on' relates to brick. making machines and `mor e particularly toimeans for fslicki'ng'the brick before removing the'latter from the vmold.

, 5 'hHeretofore considerable diflicultyhas been experienced in the use of rotary and other "known -slickersand'so called Scrapers due to the fact that in removing the surplus material-from 'the top of the mold, "it 'frequently .v Yhappened that material from` below the surface of the'mold would be lifted and rembved.

Also'it frequently happenedthat theV matcv4rialwoul/d not be slickeddown tothe top of the mold due removed." The object of vthe foregoing m dent to the' use to insufficient material being my invention 'is to. overcome entlo'ned dlsadvantages 1nc1- of Yslickers and Scrapers by 4providing 'a devicerwhich will only 'remove .2120 that material inthe mold which is above the surface of the m old.

' A lfurther object of my invention is to provide the slicker with means for removingthe surplus material orkcap from'they top of the f`f`2`5 moldin advance Vof the slicking operation.A

- Other 'and further advantages of my invention vwill `be apparent as the specification is consideredin connection l 'with 'the accompanying drawin gs, in which .f3-To vFigure 1l s an elevation `ofa portion of a ybrickvrnaking machine showing my invention applied .Figure "Figure 3/ 2 is an end elevationof Figure 1; b

Referring mo detailed modification -of the reparticularly to the drawbeams 20.

ings wherein ylike 'reference numerals desig-r nate corresponding parts throughout the several views l denotes aportion ofthe frame c of a brick machine, comprising uprights or A3 and 4.4. These shafts 9have bevel gears 11 fixedly mounted on their lupper ends which mesh with bevel gears12, on horizontally dis,- posed shaftsY 13, mounted in'bearing `15, secured to the'posts 2. A drive-'pulley 16 con-V 'nected'to any suitable source of power (not lshown)='rotat`es the shafts 13 and the latter ,in turn, through the gears 11 and 12 rotate the vertical shaftsv 9.

' Connected to the lower endsof the shafts 9 are a pair of crankarms 17, from the free ends of which-depend crank 'pins 18. These crank arms 17 are connectedto and support a slicker support 19, comprising a pair of spaced angle beamsv 20, secured to spacing blocks 2l as by bolts 22. The crank pins18 extend loosely through openings 23 in the spacing blocks, nuts 24 screwing on'the free ends of the pins 18 serving to prevent the pallet support from dropping ofthe pins. A slicker bar or plate 25 having beveled edges 26 is screwed to the Y lpallet support19 by means of countersunk headed bolts 27 which ,pass upwardly through the slicker bar 25Uand flanges 28 ofthe angle It win be noted that the Sucker-bar is p0- sitionedslight'ly above -theplane of travel of the top of the sectional mold 8 sothat relativemovement of the mold and .sllckerbar lwill cause the latter to slick the excess material from the top of the former. The height of the slicker bar above the mold and therefore the amount of pressure applied to the mold or material therein can be adjusted in an obvious manner by means of the washers 29 and the nuts 24.

In the modified form of the invention illustrated in Figure 5, a cutter bar 30 is bolted to the slicker bar support 19 by means of bolts 31. This cutter bar is preferably inclined downwardly so that the cutting edge 32 thereof is slightly below the top face of the slicker bar and preferably slightly above the bottom face of the bottom of the slicker bar. This cutting edge 32 may be modified to reduce or in some instances it may be desirable to remove the bevel edge or even reverse the bevel. The inclination of the cutter can be adjusted by employing one or more wedge shaped washers 33, so that the cutter will cut the brick making material to any desired height above t-he mold in advance of the slicking operation. The inclination of the cutter 3() is primarily of importance in that by altering the angle the working edge of the cutter can be conveniently elevated or lowered according to the kind of brick making material being used.

In the modification illustrated in Figure 6, the slicker bar 25 is formed with a bevel on its upper forward edge, which has been found desirable where material of certa-in characteristics is used.

While it is thought that the operation of the slicker will be readily understood from the foregoing description, the following brief explanation is given: After the sectional mold has been filled with brick making material, the pallet 7 with the mold 8 thereon is slid along the tracks 6 by the usual mold actuating mechanism (not shown). As the mold passes beneath the slicker bar (which may be held stationary if deemed desirable) the cap or top of the material in the mold is removed by the cutter 30, or in the event the material does not require advance cutting, and the cutter bar is dispensed with, the excess material is removed by the slicker bar. The movement of the mold continues until it is beneath the slicker bar, the latter being of substantially the same width and length as the mold, although the width of the slicker bar may be varied depending upon the character of the brick making material and the length of time that can be devoted to the slicking operation, as may be affected by the various operations of the brick machine. The movement of the mold may be arrested at this point, or continued to carry the mold from beneath the slicker, or the previous movement of the mold may be reserved for this purpose.

Where it is deemed desirable the mold may be slicked while remaining stationary on the tracks 6 by causing the slicker bar to swing with a circular motion, towards and across the mold. This movement is effected, as previously explained through the drive pulley 16, shafts 13 and 9 and crank arms and pins 17 and 18 respectively. Under certain conditions it is desirable to swing or pass the slicker bar across the mold when the latter is in motion, in which event the drive for the pulley 16 and mold pusher mechanism (not shown) will be actuated in synchronism.

Having thus described my invention, what I claim is:

1. In a brick making machine, a mold and mold support, a slicker comprising a slicker bar of substantially the same length as the mold, and means connected to opposite ends of said bar for causing the bar to move across the top of the mold with a translate-ry circular movement.

2. In a brick making machine, a mold and mold support, a slicker comprising a bar having beveled edges, a cutter carried by the slicker bar and having its forward edge beveled reversely to the bevel of the forward edge of the bar, and means for causing relative movement of said slicker and mold towards each other.

3. In a brick making machine, a mold and mold support, a slicker comprising a bar having beveled edges, a cutter carried bythe slicker bar and having its forward edge beveled reversely to the bevel of the forward edge kof the bar, and means for moving said slicker bar and cutter in a circular path across the top of the mold.

4. In a brick making machine, a mold and support therefor, a slicker bar and support therefor, the forward edge of said slicker bar being beveled on its under face, and a cutter on said bar projecting at an angle beyond 1L.and below the forward edge of the slicker 5. In a brick making machine, a mold and support therefor, a slicker bar and support therefor, the forward edge of said slicker bar being beveled on its under face, a cutter on said bar projecting at an angle beyond and below the forward edge of the slicker bar, the forward edge of the cutter being beveled on its upper face.

6. vIn a brick making machine, a mold and support therefor, a slicker bar and support therefor, the forward edge of s-aid slicker bar being beveled on its under face, a cutter on said bar projecting at an angle beyond and below the forward edge of the slicker bar and means for adjusting the angularity of the cutter bar with respect to the slicker bar.

7. In a brick making machine, a mold and support therefor, a slicker bar and support therefor, and a cutter on said bar having its forward edge below and in advance of the forward edge of the slicker bar.

8. In a brick making machine, a mold and support therefor, aslicker bar and support therefor, and a cutter von saidbar having its forward edge below and in advance ,of the forward edge of the slicker bar and means` f length as the mold, and means or causing the said member to move relatively to the mold across the top thereof with atranslatory circular movement.
